Based on prior knowledge, it is generally known that high glucose levels are associated with diabetes. However, it is important to consult medical knowledge and guidelines for the specific ranges of values considered indicative of diabetes.

Based on the task of determining whether a person has diabetes or not, we can analyze the relationship between the Glucose feature and the target variable. 

Here is a dictionary providing the possible values of the Glucose feature for each target class ('yes' and 'no'):

```json
{
	"yes": [168.0, 196.0, 200.0, 220.0, 240.0],
	"no": [90.0, 95.0, 100.0, 105.0, 110.0]
}
```

Please note that the provided values are for illustrative purposes only and may not reflect actual medical guidelines. Consulting a medical professional or referring to specific guidelines is recommended for accurate interpretations.
